PHENOL-DENATURED POLYORGANOSILOXANE WITH REDUCED PLATINUM CONTENT, METHOD FOR PRODUCING SAME, AND ORGANIC RESIN MODIFIER CONTAINING SAME

摘要

The platinum metal content decreased and by decreasing the yellowing, as an organic modifier for resin suitable phenol-modified with a polyorganosiloxane, preparation method thereof and an organic modifier for resin containing the same are provided. Phenol of the present invention the modified polyorganosiloxane is a compound of formula I is a platinum metal content of 0.9 ppm or less. Phenol of the present invention-modified polyorganosiloxanes include, for example, poly climb of the phenol compound and the formula (V) substituted hydro yarn migration reaction groups alkenyl of the formula IV seen in the presence of available platinum-containing catalyst applied to a homogeneous system Kano was added to the hydrogen siloxane, and subsequently, filtration is carried out if the activated carbon is added, filtration is carried out by use of a filter containing the activated carbon, and the group consisting of a cation which is embodied by the use of a filter capable of adsorbing filtration by subjecting to filtration alone or in combination with one or more steps selected from can be prepared by reducing the platinum metal content of the resulting product was less than 0.9 ppm.
